A Perspective from our CEO and President of the Executive Strategy Board

Spread Spectrum and VL-SNR

Enalbing efficient and reliable transmission from small antennas.

Providing high-speed connectivity through small mobile antennas can prove to be a challenge. The form factor of the antenna plays a major role in the integration, aero dynamics and fuel costs. The use of smaller antennas, such as flat panel becomes more prevalent, but it also comes with the risk of creating adjacent satellite interference when transmitting from the moving remote to the satellite. One solution comes in the form of spread spectrum, which diffuses high rate signals by “spreading out” the transmissions over greater bandwidth so less power density is required. This minimizes the interference to adjacent satellites without limiting connectivity to the target satellite.

The MxDMA waveform also incorporates Very Low Signal-to-Noise (VL-SNR) spreading MODCODs. These VL-SNR MODCODs facilitate the use of small and phased array antennas, counter deep fading effects and secure communications when the carriers are hidden in the noise.

Reduces the spectral density of the transmission to avoid interfering with adjacent satellites

Facilitates the use of small antennas for comms-on-the-move (COTM) applications

May allow carriers to be hidden under the noise to conceal traffic activity during stealth operations for secure communications
